Adding an ADU, garage conversion, or room addition in Redondo Beach means working with tight lots, older beach-adjacent housing stock, and a city permit process that rewards contractors who show up with the paperwork already in order. Fielding ADU Builders handles all three, with a written price before any work starts and a one-year written guarantee on every project. Call (361) 315-4177 and you’ll reach a live person, any hour, any day.
Why Redondo Beach Homes Are Different
Redondo Beach lots run small, especially in the Avenues and Golden Hills neighborhoods where single-story bungalows from the 1940s and 1950s sit close to the property line, often within a few feet of the neighbor’s wall. That changes how an addition or ADU gets framed, how equipment gets staged, and how much of the work has to happen indoors or under cover. Marine air also moves through everything here: most homes within a mile or so of the Esplanade carry surface oxidation on original hardware, and older foundations near the water table sometimes need a closer look before we commit to a plan. In North Redondo, where post-war tract homes dominate, the lots are modest but the setbacks tend to be more predictable, which makes room additions and detached ADUs a cleaner fit. Coastal slope conditions and the city’s coastal-zone review add a layer most interior Los Angeles County cities don’t deal with, so we build that time into the schedule from day one. If you own a place in South Redondo near Riviera Village or the Hollywood Riviera side, the street patterns and hillside grades mean every access path has to be planned before the first material order goes in.
Our Main Redondo Beach Services
Most Redondo Beach homeowners call us about one of three projects: adding a room, converting a garage, or building a full ADU. Each has its own Redondo Beach page, linked below.
Room Addition Contractor in Redondo Beach
A room addition here usually means extending a post-war bungalow outward or up, and the trick is tying the new roofline to the old one without making it look stitched on. We handle the structural engineering, the permit set, and the interior finish work under one written price. Coastal moisture means we specify materials that won’t warp or swell a year later. See the full breakdown on our Room Addition Contractor in Redondo Beach page.
Garage Conversion Contractor in Redondo Beach
Converting a garage in Redondo Beach often means working with a detached structure built in the 1950s or 1960s, with a slab that may predate current code. We evaluate what can stay and what gets replaced, then price the whole job in writing before demo starts. ADU-eligible conversions are common here because the city has streamlined the path for attached and detached garage units. Details are on our Garage Conversion Contractor in Redondo Beach page.

Some do, depending on how close the property sits to the water and whether the work triggers coastal-zone review. We check that before pricing, and we pull every permit the city requires. We don’t start work on a project that isn’t permitted.
